Online casinos match their members’ deposits with certain rates to reward them. These promotions are simply called “deposit match casino bonus”, and a 300% deposit bonus is a type of them. (As we will explain below, this promotion is also available with different match rates.) With this bonus, you will earn a balance of three times the amount of your deposit. To give a simple example, if you deposit £15, the casino will deposit £75 into your bonus balance (15 x 3). The money in your bonus balance can be used for gaming or withdrawn to your bank account after the so-called “wagering” requirements are met.
Redeeming a 300% deposit bonus is pretty easy as most of the time all you have to do is make a deposit that meets the minimum limit set by the casino. You can find out how this promotion can be triggered and what the minimum deposit limit is by reading the bonus terms. Sometimes you may need to use a code, and if this is the case, the relevant code will be stated in the bonus terms too.
Once you complete the deposit using any payment method (and apply the code if necessary), your bonus will be automatically credited to your account. It is not yet usable, but after a certain amount of money has been wagered, you can transfer the amount inside it to your real balance. This bonus is almost always offered to new members for their first deposit and can be used once.
Before using a 300% deposit bonus, it’s a good idea to find out what you can really expect from it. Because although it offers a high match rate, it has some disadvantages like all other bonuses and may not be the best choice for every player for the same reason.
To find the best 300% deposit bonus, you need to visit dozens of casinos, read the bonus terms of each, and do all of these regularly every week. This is not a practical solution: it would be better to spend your time playing games. So, if you don’t want to waste time or make the wrong choice, we recommend that you take a look at our list at the top of this page: we’ve already selected the best 300% deposit casino bonuses in the UK. You can choose any of the all the online casinos we recommend and claim your welcome bonus right now.
You usually need to make a deposit to trigger the best online casino bonuses. The process is usually automatic: as soon as the deposit is complete, the bonus (e.g., welcome bonus) will be activated automatically. This is exactly how a deposit match bonus works: in order for the casino to be able to match, a deposit must first be made.
No deposit bonuses are completely different. As you might guess from the name, these are a special and rare type of bonus that requires no deposit. To trigger them, you will usually need to create a new account and log in to it. (Sometimes you may be asked to use a special code too.) The main difference between the two promotion types is whether a deposit is required.
No deposit offers also allow you to get cash or free spins, but their number or amount is less compared to match bonuses. However, they can be used immediately, and the wagering requirement should only be completed if you can make a profit with them. So first you use the bonus, then you wager money. In match bonuses, wagering is done first, then the bonus is used.
A 300% deposit casino bonus is almost always part of a welcome package, meaning it is offered to new members. If you have browsed through some of the welcome offers so far, you must have noticed that almost all of them include a certain number of free spins. This also applies to the 300% casino bonus: if it is offered to new members (i.e., as a 300% welcome bonus), it will also include a certain number of free spins (e.g., 200). These spins can be used as soon as the deposit is completed. But keep in mind that the spins can only be used on slots, these slots may be limited by the casino, and may require separate & different wagering terms. In this respect, they are similar to no deposit free spins: if you win anything with them, you must first complete a wagering requirement in order to be able to use or withdraw your prize.
This promotion, which allows you to earn three times your deposit amount, is useful, but it is not the only option. There are other promotions that fall into the match deposit bonus category, each offering a different rate. Below you can see a list of the different match rates offered for deposit bonuses.
💎 100% casino bonus: This is also known as the “first deposit bonus” because it is the most common match rate in welcome packages. The bonus amount will be equal to the deposit amount.
💎 200% casino bonus: The match rate of this offer will double the deposit amount. It is also pretty common and offered to existing members too.
💎 400% casino bonus: You can multiply the deposit amount by 4 to see how big your bonus will be. Because it is a high match rate, this bonus is usually only available to new members.
💎 500% casino bonus: This is the highest match rate you can get: you can win a bankroll of five times the deposit amount. It is offered only to new members.
Technically, a match bonus can be used by all members (new & existing), but high match rates are only offered to new players. Therefore, a 300% deposit bonus will only be available for new members too. Usually, the match rate of existing members does not exceed 200%.
If the casino offers it to them, yes, existing members can take advantage of a 300% deposit bonus too. However, this is a rare occurrence. 300% is a high rate and is only offered to new members. Match deposit bonuses of existing members are in the range of 100% - 200%.
Regardless of the match rate, all casino bonuses work on mobile. HTML5 technology enables not only games but all services offered in a casino to run on browsers without a download. Bonuses are also a type of service and can be used from any mobile browser.
The casino decides in which games your bonus can or cannot be used. You can find out the clearest answer to this question by reading the bonus terms because each casino has a different policy. But in general, we can say that you are allowed to use this bonus in any game at the casino.
